I have been using a double uni knot to go from braid to a fluoro leader, and just recently learned a perfection loop, and accompanying loop-to-loop for fly line to fly leader. For spinning gear with a variety of bass fishing tackle and line, would the perfection loop work in braid to quickly swap leaders that are not braid?

  • I know this is an old question and answer, but it got bumped to the front page since it was edited. I'm wondering if you had pics or even a drawing? It's difficult to understand what you are doing without one.

Verdict is that it works and seems to be very strong, but it is not easy to quickly switch leaders, since the braid-half of the loop-to-loop tightens around it itself much more than the mono/fluoro side of the loop.
